Functions Required for Linear Guide Surface B1-8 Features and Types LM Guide 507E Large Permissible Load and High Rigidity [Large Permissible Load] The LM Guide has raceway grooves with a radius almost equal to the ball radius, which is signifi - cantly different from the linear bushing. As shown in Fig.1 , which compares size between the LM Guide and the linear bushing with similar basic dynamic load ratings, the LM Guide is much smaller than the linear bushing, indicating that the LM Guide allows a signifi cantly compact design. The reason for this space saving is the greater difference in permissible load between the R-groove contact structure and the surface contact structure. The R-groove contact structure (radius: 52% of the ball radius) can bear a load per ball 13 times greater than the surface contact structure. Since service life is proportional to the cube of the permissible load, this increased ball-bearing load translates into a service life that is approximately 2,200 longer than the linear bushing.

Additionally, due to the circular-arc groove design, it is capable of carrying a preload as necessary to increase its rigidity. When compared with a feed screw shaft system and a spindle in rigidity, the guide surface using an LM Guide has higher rigidity.  Example of comparing static rigidity between the LM Guide, a feed screw shaft system and a spindle (vertical machining center with the main shaft motor of 7.5 kW) [Components] LM Guide: SVR45LC/C0 (C0 clearance: preload = 11.11kN) Ball Screw: BNFN4010-5/G0 (G0 clearance: preload = 2.64kN) Spindle: general-purpose cutting spindle Table2 Comparison of Static Rigidity Unit: N/m Components X-axis direction Y-axis direction Z-axis direction LM Guide — 2400 9400 (radial) 7400 (reverse radial) Ball screw 330 — — Spindle 250 250 280 Note) The rigidity of the feed screw shaft system includes rigidity of the shaft end support bearing.

In addition, it uses LM rails in parallel on multiple axes to form a guide system with multiple-axis confi guration. Thus, the LM Guide is capable of absorbing misalignment in straightness, fl atness or parallelism that would occur in the machining of the base to which the LM Guide is to be mounted or in the installation of the LM Guide by averaging these errors. The magnitude of the averaging effect varies according to the length or size of the misalignment, the preload applied on the LM Guide and the number of axes in the multiple-axis confi guration. When misalignment is given to one of the LM rails of the table as shown in Fig.8 , the magnitude of misalignment and the actual dynamic accuracy of the table (straightness in the horizontal direction) are as shown in Fig.9 . By applying such characteristics obtained with the averaging effect, you can easily establish a guide system with high precision of motion.

As a result, sliding surfaces do not need to be reconditioned, and precision needs not be altered. Regarding lubrication, sliding guides require forced circulation of a large amount of lubricant so as to maintain an oil fi lm on the sliding surfaces, whereas the LM Guide only needs periodical replenishing of a small amount of grease or lubricant. Maintenance is that simple. This also helps keep the work environment clean. B1-16 507E Substantial Energy Savings As shown in Table6 , the LM Guide has a substantial energy saving effect.

Thus, the assembly man-hours for the LM Guide are reduced, and machines and systems incorporating the LM Guide can be produced at lower cost. The fi gure below shows an example of difference in the procedure of assembling a machining center between using siding guides and using LM Guides. Normally, with a sliding guide, the surface on which the guide is installed must be given a very smooth fi nish by grinding. However, the LM Guide can offer high precision even if the surface is milled or planed. Using the LM Guide thus cuts down on machining man-hours and lowers machining costs as a whole.

B1-18 507E Ideal Four Raceway, Circular-Arc Groove, Two-Point Contact Structure The LM Guide has a self-adjusting capability that competitors’ products do not have. This feature is achieved with an ideal four raceway, circular-arc groove, two-point contact structure. [Comparison of Characteristics between the LM Guide and Similar Products] LM Guide: Four Raceway, Circular-arc Groove, Two-point Contact Structure Other Product: Two-row, Gothic-arch Groove Four Point Contact Structure Differential slip R: Radius of curvature Ball rotation axis Contact width LM Guide Model HSR Contact width Rotation axis Rotation axis d2 d1 B A π×d1 π×d2 R d2 d1 B A d2 B’ A’ ｄ1 Fig.12 Differential slip R: Radius of curvature Ball rotation axis Contact width Contact angle Contact angle Two-row Gothic-arch groove product Contact width Rotation axis d2 d1 B A π×d1 π×d2 d2 R R d1 B A d2 d1 B’ A’ Fig.13 As indicated in Fig.12and Fig.13 , when the ball rotates one revolution, the ball slips by the difference between the circumference of the diameter of inner surface (d 1) and that of the outer contact diameter (d 2). (This slip is called differential slip.) If the difference is large, the ball rotates while slipping, the friction coeffi cient increases more than 10 times and the friction resistance steeply increases. Features and Types Features of the LM Guide B1-19 LM Guide 507E Four Raceway, Circular-Arc Groove, Two-Point Contact Structure Two-Row, Gothic-Arch Groove, Four Point Contact Structure Smooth Motion Since the ball contacts the groove at two points in the load direction as shown in Fig.12and Fig.13on B1-19 even under a preload or a normal load, the difference between d 1and d 2is small and the differential slip is minimized to allow smooth rolling motion. The difference between d 1and d 2in the contact area is large as shown in Fig.12and Fig.13on B1-19. Therefore, if any of the following occurs, the ball will generate differential slip, causing friction almost as large as sliding resistance and shortening the service as a result of abnormal friction. (1) A preload is applied. (2) A lateral load is applied. (3) The mounting parallelism between the two axes is poor. Accuracy and Rigidity of the Mounting Surface In the ideal two-point contact structure, four rows of circular arc grooves are given appropriate contact angles. With this structure, a light distortion of the mounting surface would be absorbed within the LM block due to elastic deformation of the balls and moving of the contact points to allow unforced, smooth motion. This eliminates the need for a robust mounting base with high rigidity and accuracy for machinery such as a conveyance system. With the Gothic-arch groove product, each ball contacts the groove at four points, preventing itself from being elastically deformed and the contact points from moving (i.e., no self-adjusting capability). Therefore, even a slight distortion of the mounting surface or an accuracy error of the rail bed cannot be absorbed and smooth motion cannot be achieved. Accordingly, it is necessary to machine a highly rigid mounting base with high precision and mount a high precision rail. Rigidity With the two-point contact, even if a relatively large preload is applied, the rolling resistance does not abnormally increase and high rigidity is obtained. Since differential slip occurs due to the four-point contact, a suffi cient preload cannot be applied and high rigidity cannot be obtained. Load Rating Since the curvature radius of the ball raceway is 51 to 52% of the ball diameter, a large rated load can be obtained. Since the curvature radius of the gothic arch groove has to be 55 to 60% of the ball diameter, the rated load is reduced to approx. 50% of that of the circular arc groove. Difference in Rigidity As shown in Fig.14 , the rigidity widely varies according to the difference in curvature radius or difference in preload. Curvature radius and rigidity Applied load (kN) Preload and deflection Displacement curve of HSR30 0 clearance Magnitude of the preload: 5kN Deflection (Rigidity) (μm) Rigidity (N/μm) Comparison of rigidity by curvature (per ball) Ball diameter (mm) 60 40 20 0 10 20 10 8 6 4 2 0 2 4 6 8 10 12 R=0.6Da R=0.55Da R=0.52Da Fig.14 Difference in Service Life Since the load rating of the gothic arch groove is reduced to approx. 50% of that of the circular arc groove, the service life also decreases to 87.5%. B1-20 507E [Accuracy Error of the Mounting Surface and Test Data on Rolling Resistance] The difference between the contact structures translates into a rolling resistance. In the gothic arch groove contact structure, each ball contacts at four points and differential slip or spinning occurs if a preload is applied to increase rigidity or an error in the mounting precision is large. This sharply increases the rolling resistance and causes abnormal wear in an early stage. The following are test data obtained by comparing an LM Guide having the four raceway, circular-arc groove two-point contact structure and a product having the two-row, Gothic-arch, four-point contact structure. [Sample] [Conditions] (1) LM Guide SR30W (radial type) 2 sets HSR35A (4-way equal-load type) 2 sets (2) Two-row Gothic-arch groove product Type with dimensions similar to HSR30 2 sets Radial clearance: 0m Without seal Without lubrication Load: table mass of 30 kg Data 1: Preload and rolling resistance When a preload is applied, the rolling resistance of the Gothic-arch groove product steeply increases and differential slip occurs. Even under a preload, the rolling resistance of the LM Guide does not increase.

With the Gothic-arch groove product, the rolling resistance is 34 N when the parallelistic error is 0.03 mm and 62 N when the error is 0.04 mm. These resistances are equivalent to the slip friction coeffi cients, indicating that the balls are in sliding contact with the groove.

Then, measure the rolling resistance. If there is a height difference between the rails, moment will act on the LM block. If the LM Guide’s groove is the Gothic-arc groove, this will cause spinning. The LM Guide with the circular-arc groove is capable of absorbing the error caused by the height difference between rails as great as 0.3/200 mm, where its rolling resistance will not increase signifi cantly.

Angular Ball Bearings Mounted Front-to-front (DF type) Angular Ball Bearings Mounted Back-to-back (DB type) DF Type Four-row Angular Contact (LM Guide) Four-row Gothic-arch Contact An LM ball guide mounted on a plane receives a moment (M) due to an error in fl atness or in level or a defl ection of the table. Therefore, it is essential for the guide to have self-adjusting capability. LM Guide Model HSR Similar Product of a Competitor Mounting error Distance from the application point Distance from the application point Deflection Deflection Table M M Distance from the application point Distance from the application point Deflection Deflection Mounting error Block M M Since the distance from the application point of the bearing is small, the internal load generated from a mounting error is small and the self-adjusting capability is large. Since the distance from the application point of the bearing is large, the internal load generated from a mounting error is large and the self-adjusting capability is small. With an LM ball guide having angular ball bearings mounted back-to-back, if there is an error in fl atness or a defl ection in the table, the internal load applied to the block is approx. 6 times greater than that of the frontto-front mount structure and the service life is much shorter. In addition, the fl uctuation in sliding resistance is greater. Features and Types Features of the LM Guide B1-23 LM Guide 507E
